Water pump replacement - brands and quality?

[oz_tom]

Hi All,

 

I'm looking for any advice on brands and quality for replacement water pumps. What are people using?

 

There doesn't appear to be a hard and fast rule of who/what to avoid...

 

Options I can see online:

• GRAF - https://www.blunttech.com/shop/replacement-parts/cooling-system/W0133-1621429-GRA
• GEBA - https://www.blunttech.com/shop/replacement-parts/cooling-system/W0133-1621429-GEB
• HEPU - https://www.pelicanparts.com/catalog/SuperCat/5465/BMW_5465_WATPMP_pg1.htm#item1
• GATES - https://www.rockauto.com/en/catalog/bmw,1973,2002,2.0l+l4,1010754,cooling+system,water+pump,2208
• GMB - https://www.rockauto.com/en/catalog/bmw,1973,2002,2.0l+l4,1010754,cooling+system,water+pump,2208
• AIRTEX - https://www.rockauto.com/en/catalog/bmw,1973,2002,2.0l+l4,1010754,cooling+system,water+pump,2208
• OEM

 

There are also references to a Bosch and AC Delco pump but I haven't located stock.

 

Any help greatly appreciated!

Hello, i am using the graf 2002 pump on my e21 engine because it was easy to get here in germany. Finish looks well for me. What i can say for sure is: do not ever use airtex pumps in any engine. A very bad engine damage occured to some of my cars when a freeze plug falls out off the pump body into the toothbelt drive. That happens after a few month!

I would use the first three you list, in the reverse order- Hepu, Geba, then Graf.   For no good reasoning on the order.

 

Everything else is going to be junk, or one of those three in a different box, or in a baggie costing 6x as much.
